Jo - am I right in thinking you are only missing BL-3 M1, M4 and M7 to make this a master? I'm sure we Yaks can rustle together some of those for you - I'm not at my place this weekend but if you remind me (and please please please do!) I will check my spares. At present they aren't doing anyone any good just sitting there as spares.
I will email myself as a reminder, so remind me again in a few days
